After they have been removed from their parents and send to a camp to be brainwashed, two girls connect over an act of institutional rebellion. One suffers for it, and one goes on to live her life as she is supposed to—but will she be satisfied with leaving things alone?

Three girls in three different worlds, ranging from New York City to a fantasy kingdom, all grow diamonds in their bodies when they are sad, and each is exploited for this in a different way. As they grow older, this ability determines the shape and outcome of their lives.
